The husband of White House adviser Kellyanne Conway is poised to be nominated to lead the Justice Department’s civil division, a powerful post overseeing the federal government’s lawsuits on a wide variety of issues, including defending President Trump’s executive order on immigration.

White House officials plan in coming days to announce the nomination of George Conway, a New York lawyer, according to people familiar with the matter.

Conway has worked for decades at the law firm of Wachtell, Lipton, Rosen & Katz, specializing in securities litigation and other corporate legal issues. His name had repeatedly surfaced as being under consideration for a number of jobs at the Justice Department, including solicitor general, who oversees the government’s cases before the Supreme Court. His expected nomination to lead the civil division was first reported by the Wall Street Journal.

Kellyanne Conway is one of Trump’s most high-profile aides, appearing frequently on television to promote and defend White House policies.

The Justice Department’s civil division is an important but mostly behind-the-scenes part of the government. Its lawyers are responsible for defending federal policies and agencies in court, and for pursuing alleged wrongdoing by corporations.

During the Obama administration, the civil division racked up tens of billions of dollars’ worth of financial penalties against major corporations. Some of those settlements resolved probes of international banks for their handling of residential mortgage-backed securities that contributed to the financial collapse of 2008. Other settlements stemmed from investigations into whether pharmaceutical companies sold billions of dollars of prescription drugs under false pretenses.
